g98l problems

Hi Luis,

The Linux kernel has traditionally fairly small limit for the shared
memory segment size (SHMMAX), and this needs to be increased. On my
dual Xeon (with 2 Gb memory) I have set it to 0.5 Gig, while on some
other 2Gb Xeons in our department it is set to 1Gb. This seems to work
fine.
The way to do it permanently is to put (as root) the lines
# Increase max shared memory
kernel.shmmax=536870912
into /etc/sysctl.conf before rebooting.
The temporary solution is
echo 536870912 > /proc/sys/kernel/shmmax
Hope this helps,
Tanja
